Bill Monroe (September 13, 1911 – September 9, 1996) developed the style of country music known as bluegrass, which takes its name from his band, the "Blue Grass Boys," named for his home state of Kentucky. Monroe's performing career spanned 60 years as a singer, instrumentalist, composer and bandleader. He is often referred to as "the father of bluegrass."
These are photos from concerts where Bill Monroe played, so they may be of other bands that played the concert as well.
